What is the _wix_browser_sess cookie?
_wix_browser_sess is an HTTP cookie set automatically by Wix's infrastructure on any website created and hosted on the platform. It appears as soon as a visitor loads the page, regardless of whether the cookie banner is accepted, because it is part of the platform's core engine.
It is managed directly by Wix (Wix.com Ltd.), not by the site owner, and its presence is tied strictly to the fact that the site runs on Wix infrastructure (editor, templates, Wix Stores, Wix Bookings, etc.).
What data it stores
The cookie stores a technical, randomly generated session identifier used by Wix's servers to recognize requests coming from the same visitor during a browsing session. It is not publicly documented to contain personal data such as a name or email address.
The exact value format is not officially published by Wix and may vary. Data is exchanged between the visitor's browser and Wix's servers to keep the page, forms, and interactive components working correctly.
What it is used for
Its main purpose is technical: maintaining browsing session state so that dynamic elements of the site (shopping cart, forms, password-protected areas, Wix Apps components) behave consistently throughout the visit.
Without this cookie, some Wix site features may not work correctly, since the platform relies on it to link successive requests to the same browser session.
Does it require consent?
Under CookieFix's classification, _wix_browser_sess is categorized as strictly necessary. As a session cookie used for the basic functioning of the site's technical infrastructure, it falls under the exemption in Article 5 of the ePrivacy Directive (transposed into Romanian law via Law 506/2004), which does not require prior consent for cookies strictly necessary to provide a service explicitly requested by the user.
The site administrator does not need to obtain consent for this cookie but must still list it in the cookie policy, stating the provider (Wix), category (necessary), and duration (session), in line with GDPR transparency requirements.
How to block or delete _wix_browser_sess
A visitor can delete or block this cookie from browser settings (Chrome, Firefox, Edge, Safari – the cookie and site data management section). Blocking it may affect the correct functioning of the Wix site, including navigation or forms.
Because it is strictly necessary, this cookie should not, and generally cannot, be blocked via a consent banner without breaking site functionality. A CMP like CookieFix instead handles automatic blocking, until consent is given, of scripts from categories that actually require visitor consent (statistics, marketing), leaving strictly necessary cookies like this one to work normally.
